Calcined Kaolin is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles. In plastics calcined kaolins are used in PVC cables to improve electrical performance and in its coated form as a functional filler in engineering thermoplastics.
Diatomaceous earth (DE or diatomite) is a naturally occurring, soft, siliceous sedimentary rock (skeletal remains of single-celled aquatic plants called diatoms) that is easily crumbled into a fine white to off-white powder. Depending on the granularity, this powder can have an abrasive feel and has a low density as a result of its high porosity.
Kaolin (china clay) is a hydrated aluminium silicate crystalline mineral (kaolinite) formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape and chemical inertness.
Mica are a group of lamellar, silicate minerals. Mica deposits are mined for mica only or in combination with other minerals such as kaolin or feldspar. We can differentiate them from other silicate minerals mainly by their high aspect ratio and elasticity. Using a variety of selection and processing methods mica are separated from the other minerals, presenting a wide range of particle sizes.
